What estimated tax payments are and who needs to make them
Estimated tax payments are quarterly payments you send to the IRS when you expect to owe more than $1,000 in taxes for the year and no employer is withholding from your paycheck. The IRS calls them "estimated" because you calculate them based on your best guess of what you will earn and owe — you do not know the exact number until you file your return.
You need to make these payments if you are self-employed, have investment income, receive rental income, or work as a contractor or freelancer. If you have a W-2 job where taxes are already withheld from your paycheck, you typically do not make estimated payments. The same applies if you expect to owe less than $1,000 when you file.
The IRS charges penalties and interest if you do not pay enough throughout the year, even if you end up with a refund when you file. Making quarterly payments spreads the cost across the year and keeps you out of penalty territory.
Key Takeaways
- Estimated tax payments are due four times per year on specific dates: April 15, June 15, September 15, and January 15 of the following year.
- You calculate each payment using Form 1040-ES, which walks you through your expected income, deductions, and tax liability for the full year.
- You can pay online through IRS Direct Pay or the Electronic Federal Tax Payment System (EFTPS), by mail with a voucher, or by phone.
- If you miss a payment or pay too little, the IRS will charge penalties and interest when you file your return, even if you eventually get a refund.
- You can adjust your payments if your income changes mid-year — you do not have to stick with the same amount all four quarters.
The four payment due dates each year
The IRS divides the tax year into four quarters, each with its own payment important date. These dates do not change year to year, though they may shift by one day if they fall on a weekend or holiday.
| Quarter | Income Period | Payment Due Date |
|---|---|---|
| First | January 1 – March 31 | April 15 |
| Second | April 1 – May 31 | June 15 |
| Third | June 1 – August 31 | September 15 |
| Fourth | September 1 – December 31 | January 15 (of the following year) |
Mark these dates on your calendar now. The IRS does not send reminders, and missing even one payment triggers penalties. If April 15 falls on a Saturday, the important date becomes Monday, April 17. If it falls on a Sunday, it becomes Monday, April 16. The same rule applies to the other three quarters.
How to calculate your estimated tax payment using Form 1040-ES
The IRS provides Form 1040-ES specifically for calculating estimated payments. You can read it free from IRS.gov. The form includes a worksheet that walks you through four steps: estimate your total income for the year, subtract deductions and credits, calculate your total tax, and divide by four to get each quarterly payment.
Start by listing all income you expect to receive: self-employment income, rental income, capital gains, interest, dividends, and any other taxable income. Be realistic. If you underestimate on purpose, you will owe penalties. If you overestimate, you will get a refund when you file your return.
Next, subtract your deductions. If you take the standard deduction, use that number. If you itemize, use your itemized deduction total. Then subtract any tax credits you expect to claim — the Earned Income Tax Credit, child tax credits, education credits, and so on. The result is your estimated taxable income.
Use the tax tables in Form 1040-ES to find your total tax liability for the year. Divide that number by four. That is your quarterly payment amount. You can pay the same amount each quarter, or you can adjust if your income changes — for example, if you earn most of your income in the fall, you can pay less in the spring and more later.
Payment methods: online, by mail, or by phone
Online payment through IRS Direct Pay is the fastest and most reliable method. Go to IRS.gov, find the Direct Pay link, and enter your payment information. You choose the payment date (it can be up to 120 days in the future), and the IRS deducts the money directly from your bank account. There is no fee. You receive a confirmation number when ready.
The Electronic Federal Tax Payment System (EFTPS) is another online option. You enroll once at EFTPS.gov, then schedule payments whenever you need to. EFTPS also deducts from your bank account with no fee. Some people prefer it because it stores your payment history in one place.
Credit card or debit card payment is possible through third-party processors approved by the IRS. Search "IRS payment by card" on IRS.gov to find the current list. These processors charge a fee — usually 1.87% to 2.35% of your payment — so this method costs more but may be worth it if you want to earn credit card rewards.
Payment by mail requires Form 1040-ES vouchers. Print the voucher for the quarter you are paying, write your name, address, Social Security number, and the payment amount on it, and mail it with a check to the address shown on the form. Mail payments take longer to process and offer no confirmation, so keep a copy for your records.
Payment by phone is available by calling the IRS at 1-800-829-1040, but this method is slower and you cannot schedule payments in advance. Use it only if you cannot access online payment.
What happens if you miss a payment or pay too little
If you do not make a quarterly payment or pay less than you should, the IRS charges both a penalty and interest on the shortfall. The penalty is calculated as a percentage of the unpaid amount and increases the longer the money is late. Interest is charged at a rate set by the IRS each quarter — it changes but is typically 8% per year.
You do not owe a penalty if your total tax liability for the year is less than $1,000, even if you paid nothing during the year. You also do not owe a penalty if you paid at least 90% of your 2024 tax liability through quarterly payments, or at least 100% of your 2023 tax liability (110% if your 2023 adjusted gross income was over $150,000). These are called the "safe harbor" rules.
When you file your return, the IRS calculates the penalty and interest owed and adds it to your bill. If you are expecting a refund, the IRS subtracts the penalty and interest from it. You cannot avoid this by filing late or paying late — the penalty is based on how much you underpaid during the year, not on when you file.
Adjusting payments if your income changes during the year
You do not have to pay the same amount every quarter. If your income changes — you land a big contract, lose a client, or have an unusually profitable month — you can recalculate and adjust your remaining payments.
Use Form 1040-ES again with your updated income estimate. Calculate what you should have paid through the end of the current quarter, subtract what you have already paid, and divide the remainder by the number of quarters left in the year. That becomes your new quarterly payment.
For example, if you paid $2,000 per quarter for the first two quarters but then realize you will earn significantly less than expected, you can recalculate in July and pay less for the third and fourth quarters. The IRS will not penalize you for underpaying the first half of the year if you catch up in the second half.
Keep records of your recalculations. When you file your return, you may need to show the IRS that you adjusted your payments based on a reasonable estimate of your income at the time.
Frequently Asked Questions
What if I cannot pay the full amount by the due date?
Pay what you can by the important date. The IRS will charge interest and penalties on the unpaid portion, but paying something is better than paying nothing. You can also set up a payment plan after you file your return to pay the remaining balance over time.
Do I need to make estimated payments if I have a side business but also work a W-2 job?
Only if your total tax liability from all sources will exceed $1,000 and you do not have enough withheld from your W-2 paycheck to cover it. Talk to your W-2 employer about increasing your withholding instead — that may be simpler than making quarterly payments.
Can I pay estimated taxes for my spouse if we file jointly?
Yes. You can make one payment that covers both of your estimated liabilities, or you can make separate payments. Either way, the payment must be made in the name of the person whose income it covers, or in both names if it covers both of you.
What if I overpay my estimated taxes?
You will receive a refund when you file your return. You can also request a refund of overpayment before the year ends by filing Form 1040-ES with a note explaining the overpayment, though most people wait and claim it on their return.
Do I need to make estimated payments if I am retired and living on investment income?
Only if your investment income will result in a tax liability of more than $1,000 for the year. If you have Social Security, pensions, or other income with withholding, you may be able to increase that withholding instead of making quarterly payments.
